From 2007 to 2017 Ford produced the third-generation of the Ford Expedition. It was powered by a 5.4L Triton V8 engine paired with a six-speed automatic transmission until 2015 when the V8 was replaced with a more powerful and efficient 3.5L twin-turbo EcoBoost V6.
@royoatis that will depend on where the oil is coming from. What have you already checked? What exact year and engine is your Expedition?
